Officers responded around 11:30 a.m. to reports of multiple gunshots in the 400 block of Railroad Avenue, police said.

Officers arrived to find Delgadillo-Paredes suffering from a gunshot wound to his buttocks, said South San Francisco police Sgt. Sean Curmi. Medical crews transported the man to a trauma center. He is expected to fully recover, Curmi said.

Solorio was there with Delgadillo-Paredes and another adult when police arrived, Curmi said. Investigators determined Solorio and Delgadillo-Paredes were arguing when Solorio allegedly took out a handgun and shot him.
